They need to be offline before the snapshot takes place. Yes, they are still mounted when I take a snapshot, I must have missed that in the docs, that in itself poses a problem as I then cant umount the volumes without killing services. I'd understood the snapshotting process as being able to snapshot a live filesystem, and then mount the snapshot to perform backups from it instead of the live filesystem. Whats the purpose of the --size arg to lvcreate when taking a snapshot, I thought it was a buffer to hold data that'd normally be written to disk but cant when the snapshot exists? I'm confused. > -- > aRDy Music > http://www.ardynet.com
